Filed: 1993-07-27
Abstract: PURPOSE:To provide a liquid crystal display device which improves the visual field angle of the liquid crystal display device without degrading display grade and reliability and can be produced at a low cost. CONSTITUTION:Slit apertures 18 are formed at >=1 points per 1 picture element on a counter electrode 15 on a wiring substrate 32 by directing their long side direction perpendicularly to the average orientation direction of the liquid crystal molecules projected on the substrate.

Abstract: PURPOSE:To suppress heating and to secure safety by setting the potential on the input side of a constant voltage IC at a ground level or a value near to it by energizing a Zener diode connected between the input and the output terminals of the IC when heat is generated in the constant voltage IC by overloading. CONSTITUTION:When the output side of the constant voltage IC 55 is short- circuited to the ground due to an unknown reason, for example, the generation of the short-circuit between electrodes in an output capacitor C2, or the output current value of the constant voltage IC 55 goes to an excessive value due to the overloading in a stabilized DC voltage supply circuit 3, a voltage to be impressed between the cathode and anode of the Zener diode ZD2 exceeds a Zener voltage, which energizes the Zener diode ZD2, and the input side of the constant voltage IC 55 drops to the ground potential. Therefore, the power-on signal output terminal P-OH of a microcomputer 54 goes to an 'L' level. A switching transistor Q10 is turned off at the timing of the fall of the 'L' level, and a relay contact 58a is opened, which stops the operation of a power source circuit 60.
